JavaScript MOJO with chakra
summary
Chakra ships a new interpreter and compiler that run together so hot functions get background JIT compilation on a second core, yielding concrete wins: integer-number representation, cached per-callsite properties, native UTF‑8 and much lower DOM marshalling cost. Measured results show a tight pattern match loop falls from ~250 ms to ~100 ms (about 2× speed), page load CPU time drops and typical page time goes from ~6s to <5s, and the team submits 5,500+ ES5 tests to improve interoperability.
